If you have covered function tranformations
is an exponential function, likely something like

but shifted upwards by 3 units and with a coefficient multiplying "x" something like "2"
so... try graphing in your calculator
200 - 8x
200 - (28-12)(.5)x200 - (16)(.5)x200 - 8x
The value of the bike at any year n is calculated through the equation,
At = (A1) x (1 - r)^n
Substituting the known values,
At = ($500) x (1 - 0.25)^5 = $118.65
Thus, the bike would cost only $118.65 after 5 years and the answer is letter B.
